Rolex Datejust 31 – Ref. Case Shape: Round. 278344RBR-0022
The Rolex Datejust 31 Ref. 278344RBR-0022 is an elegant women’s timepiece that blends classic Rolex craftsmanship with refined jewellery details. Crafted in White Rolesor — the union of Oystersteel and 18k white gold — this 31 mm Datejust is distinguished by a diamond-set bezel, a delicate pink dial with applied Roman numerals, and a comfortable Jubilee bracelet. It balances daily wearability with a jewel-like presence suited to formal occasions and everyday luxury.
Case & Materials
The 31 mm Oyster case uses corrosion-resistant Oystersteel, while the bezel and selected appointments are executed in 18k white gold. The diamond-set bezel is precision gem-set to Rolex standards, framing the dial with a luminous halo that catches light without overwhelming the watch’s proportions. The case construction includes a Twinlock screw-down crown and a secure screw-down back, providing 100 meters of water resistance.
Dial & Hands
This reference features a pink sunray-finished dial that subtly shifts tone as it meets changing light. Applied Roman numerals in white gold offer a timeless, classical look while polished dauphine hands ensure clear legibility. The date aperture at three o’clock is topped by Rolex’s Cyclops lens, magnifying the date for quick reading. The combination of pink tone and Roman numerals gives the watch a feminine yet traditionally inspired aesthetic.
Movement & Performance
Under the dial beats Rolex’s in-house Calibre 2236, a self-winding mechanical movement featuring a Syloxi silicon hairspring and Paraflex shock absorbers. The calibre is certified as a Superlative Chronometer after casing, delivering exceptional precision within −2/+2 seconds per day. With approximately 55 hours of power reserve and robust engineering, the movement offers reliability and smooth daily performance suitable for modern lifestyles.
Jubilee Bracelet & Comfort
The Datejust 31 Ref. 278344RBR-0022 is presented on a five-piece link Jubilee bracelet crafted from Oystersteel. Celebrated for its supple feel and elegant drape, the Jubilee bracelet elevates the watch’s comfort and style. A concealed Crownclasp secures the bracelet for a seamless look on the wrist, reinforcing the watch’s jewellery-like presentation while remaining practical for everyday wear.
Key Attributes & Why It Stands Out
This reference combines hallmark Rolex engineering with refined decorative touches. Its diamond-set bezel provides luxurious sparkle, while the pink dial and Roman numerals deliver a distinctive feminine character. White Rolesor unites the resilience of steel with the lustre of gold, and the Calibre 2236 brings modern performance. At 31 mm, the watch is perfectly balanced for smaller wrists, offering presence without excess.
Conclusion
The Rolex Datejust 31 Ref. 278344RBR-0022 is a sophisticated choice for those seeking a compact luxury watch that reads as both a high-quality timekeeper and an elegant piece of jewellery. Its thoughtful combination of materials, classical Roman numerals, and Rolex precision makes it a compelling option for collectors and wearers who value timeless style and dependable engineering. Meticulous gem-setting, enduring materials, and Rolex aftersales support further enhance its appeal, making Ref. 278344RBR-0022 an investment in both style and lasting quality for generations. A classic in any collection and heritage.
